Product Overview
Molded from translucent high-density polyethylene, the Nalgene 2104-0008 is an 8 oz (250 mL) wide-mouth laboratory bottle engineered for storing and handling liquids, dry reagents, and specimen samples. A wide neck opening allows direct access with spatulas, scoops, or pipettes without requiring a funnel. Paired with a linerless 43 mm polypropylene screw closure, the container maintains a leakproof seal across standard laboratory, field sampling, and benchtop chemical applications.

Frequently Asked Questions
Can this HDPE bottle be autoclaved?
No. High-density polyethylene softens and deforms at standard autoclave temperatures. Polypropylene labware is required for autoclaving.
What is the inner diameter of the bottle opening?
The inner neck diameter measures 33 mm, allowing direct access with spatulas, scoops, or transfer pipettes.
Does the screw closure require a separate sealing liner?
No. The Nalgene closure uses an integrated sealing ring molded directly into the polypropylene cap, providing a leakproof seal without a separate liner that could degrade or contaminate contents.
Can this bottle be used for long-term freezer storage?
Yes. The bottle and closure are rated for temperatures down to -100°C (-148°F), suitable for sub-zero freezer specimen storage. When freezing liquids, fill only to 80% capacity to allow for expansion. Each piece costs less as the order grows - see the price-break table on this page.
There is a reason the lab bench standardized on Nalgene decades ago: when you tighten that cap down, whatever is inside stays inside until you decide otherwise.
